本文用Onsager方法研究了长余辉大分子溶液中的取向有序。它示出的液晶转变发生在显着较高的浓度和在过渡点的顺序参数是远远小于自由接合段的模型。结果表明，半柔性链解的取向有序性本质上取决于柔性链沿链轮廓沿着的分布。
The orientational ordering in the solution of long persistent macromolecules is studied by means of the Onsager method. It is shown that the liquid-crystalline transition occurs at significantly higher concentrations and that the order parameter at the transition point is much smaller than for the model of freely-jointed segments. It is concluded that the orientational ordering in the solutions of semiflexible chains depends essentially on the flexibility distribution along the chain contour.
